The Church of Saints Ambrose, Gervasius, and Protasius in Bisentrate was built in 1520 on the site of the original church dedicated to Saint Ambrose, mentioned as a chapel in the Notizia Cleri Mediolanensis  dated 1398. The church is described as follows in the records of the pastoral visits of 1572 and 1579: “square room – single altar placed to the east consistent with canonical norms – earthen floor – wooden beam roof – on the front to the left of the entrance, a small bell tower with a single bell, with votive paintings on the walls, not worthless if, in his report, the visiting official recommends plastering only where not painted.”

The building is a single nave, with a rectangular plan. The facade is gabled with a central entrance and an oculus above it. At the back, to the left, stands the bell tower. The nave is lit by a series of rectangular openings along the sides. A lunette opening is also present on the right side of the small square-plan presbytery, covered by a vaulted ceiling. The walls and the vault of the presbytery as well as a portion of the wall to its right feature decorative paintings.

In the 1970s, the altar was repositioned to face the congregation, and its frontal was decorated with a reproduction of the Last Supper. The ambo is movable, made of metal and wood. The previous wall altar machine is still present.

The dedication to the three Milanese saints suggests a deep connection with the Archdiocese of Milan and the Ambrosian tradition. Despite its simplicity, the church is likely to have featured votive or decorative elements related to the patron saints.

Historical Context of Bisentrate

Bisentrate has ancient origins, as proved by archaeological finds like a Roman tomb of the imperial period discovered within the village itself.

In addition, Fontanile Cavetto springs in Bisentrate and this shows the village’s connection with the territory.

The presence of both subsidiary churches and large religious complexes, such as the Basilica of San Francesco in Pozzuolo Martesana (one of the first Franciscan settlements in Lombardy), highlights the Martesana’s historical and religious valuable heritage.
